Abstract: A water treatment apparatus provides treatment of water to remove, for example, hydrogen sulfide and iron, dissolved or dispersed in ground water. The system is provided with water from a conventional well and pump and includes a venturi-type aerating device which may be supplied air by a compressor. The air and water mixture are supplied to a first aerating tank through a spray nozzle which reduces the aerated water flow to a mist of fine droplets. A draw tube adjacent the bottom of the first tank provides the water to a treatment tank which is partially filled with a chemically active filtration media. The treatment tank is also equipped with a draw tube which draws off the treated water at the bottom of the tank and provides it to a third, deaerating tank wherein the air separates from the water and is purged to the atmosphere. Reduction of hydrogen sulfide content from 30 ppm to less than 5 ppm has been achieved.

Abstract: An apparatus for removing dissolved hydrogen sulfide from water including an atomizing tank defining an open end. A manifold is positioned adjacent the open end. The manifold defines an inlet channel having a first inlet port and a second inlet port. The first inlet port is in communication with aerated water containing dissolved hydrogen sulfide. An atomizing nozzle is in communication with the second inlet port for atomizing the water to cause the dissolved hydrogen sulfide to react with oxygen in the air to form sulfate in the atomizing tank. At least one filtering tank is in communication with the atomizing tank for filtering the sulfate from the water. The method of the present invention includes the steps of: (a) aerating water containing dissolved hydrogen sulfide with air at a predetermined pressure; and (b) atomizing the water to cause the dissolved hydrogen sulfide to react with oxygen in the air to form sulfate.
